As our summers get hotter, our air conditioners have to work harder. The Mistbox is here to help. It attaches to your outdoor unit and automatically knows when your A/C kicks on, spraying a fine mist that cools the incoming air, so your unit doesn't have to work as hard or run as long. It's simple to install, with just a few necessary pieces and connections, and it uses a wind turbine mounted on top to generate power and charge the battery — after all, there's no sense in lowering your A/C bill with another gadget that's eating up electricity itself. You can pay for the hardware with a monthly subscription that includes unlimited replacement water filters, or buy it up front and pay less per month.

Window air units might keep you cool, but their design is the stuff of nightmares: heavy, awkward boxes that block your view, are a pain to install, and sound like a robot with pertussis. The Noria Air Conditioner is a reimagining of the window unit from the ground up, with the aim of alleviating all those problems. Easy to install, it has a low profile design that's less than 6" tall and lets you reclaim the view from your window. Quiet, efficient fans direct air upwards, creating a convective cycle that spreads the coolness throughout the room, and a fresh air mode lets in outside air on cool nights. You can set the temperature via the simple dial on the front, or open the app to access smart features like a scheduling system. And thanks to a special frame that lets you close the window before sliding the main unit into place, you don't have to worry about it tumbling through the open window onto unsuspecting objects/animals/people below.

You took time picking out the right fireplace. So don't go lighting it with tools that look like they belong in an 1800s saloon. The George & Willy Firestarter is as effective as it is aesthetically pleasing. The kit includes a simple retangular vessel that holds lamp oil and a matching firestone rod. You fill the vessel with the included oil, let the stone soak, roll it in the ashes, light it, set it underneath your wood for 15 minutes or so, and you're all set. The vessel also serves as a holder for the firestone, and both are finished in unassuming matte black.

Just like your mattress, your pillow has a big effect on the quality of your sleep. And just like their comfortable mattress, the Casper Pillow is designed to make sure you rest well. It provides both comfort and support regardless of your sleeping position, with a firm inner core and a softer outer shell. Essentially it's a pillow within a pillow. It also won't pancake or lose shape thanks to the silky fibers it was constructed with, and is finished with breathable percale cotton to keep things cool. Take advantage of the 100 night trial and if you don't love it, Casper will give you a free refund.

We spend on average 7.5 hours a day staring at a screen, and our eyes are slowly paying the consequences. Founded by former analysts, Felix Gray makes the best of the situation. Available in non-Rx and reading options, their clear lens filters the most harmful wavelengths of blue light and eliminates glare to combat eyestrain and headaches. They offer multiple frames handcrafted from premium Italian acetate to suit all face shapes and personal styles.

Now on its third generation, the Nest Thermostat isn't the only smart thermostat around anymore — but it's still one of the best. The latest model has a screen that's higher-res and 40 percent larger than the 2nd-gen, a fact that's put to full advantage by Farsight, a feature that displays the target temperature or time in large, easily-readable type when you walk in the room. It's thinner, too, still integrates well with the company's smoke/CO2 detector and cameras, and can now sense problems with your furnace ahead of time, so you're not left with an outrageous maintenance bill, or worse, a non-functioning heater.

With warmer weather just around the corner, it's time to re-evaluate your ceiling fan situation. Haiku with SenseME from Big Ass Fans is the world's first smart fan, with on-board sensors and microprocessors that monitor room conditions and occupancy so the fan can adjust automatically as conditions change. Haiku can reduce utility bills on its own, but it also works with the Nest Learning Thermostat to make saving even easier--and just like Nest, the fan learns your preferences and adjusts on the fly. It can even connect with UP by Jawbone fitness trackers to make your bedroom more comfortable for a better night's sleep. The sleek, minimalist fan is controlled by something we all have--a smartphone--so you can say goodbye to clunky pull chains and wobbly, ugly ceiling fans and hello to the future.
